2013-01-30...in light of recent activity related to llvm.memcpy flags. I want toAndrew Trick
prevent an llvm developer from mistakenly thinking that just because the intrinsic has volatile flags that volatile operations can be converted to or folded into them. Platforms may rely on volatile loads and stores of natively supported data width to be executed as single instruction. When compiling C, this expectation likely holds for l-values of volatile primitive types with native hardware support, but not necessarily for aggregate types. The frontend upholds these expectations, which are not specified in the IR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173974 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30Linker: correctly link in dbg.declareManman Ren
Given source IR: call void @llvm.dbg.declare(metadata !{i32* %argc.addr}, metadata !14), !dbg !15 we used to generate call void @llvm.dbg.declare(metadata !27, metadata !28), !dbg !29 !27 = metadata !{null} With this patch, we will correctly generate call void @llvm.dbg.declare(metadata !{i32* %argc.addr}, metadata !27), !dbg !28 Looking up %argc.addr in ValueMap will return null, since %argc.addr is already correctly set up, we can use identity mapping. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173946 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30This patch reworks how llvm targets set Jack Carter
and update ELF header e_flags. Currently gathering information such as symbol, section and data is done by collecting it in an MCAssembler object. From MCAssembler and MCAsmLayout objects ELFObjectWriter::WriteObject() forms and streams out the ELF object file. This patch just adds a few members to the MCAssember class to store and access the e_flag settings. It allows for runtime additions to the e_flag by assembler directives. The standalone assembler can get to MCAssembler from getParser().getStreamer().getAssembler(). This patch is the generic infrastructure and will be followed by patches for ARM and Mips for their target specific use.
